Furnace Repair in Los Angeles
Power Pro Plumbing, Heating & Air repairs gas and electric furnaces of every brand across Los Angeles and Orange County, with same-day service and true 24/7 availability at no extra charge.
Furnaces almost always warn you before they fail: strange noises, weak airflow, odd smells, short cycling, or heat that never quite arrives. Catching those signs early usually means a smaller, cheaper repair — and a safer one, since some furnace faults (like a cracked heat exchanger) carry carbon monoxide risk.
Our certified technicians diagnose the actual fault, quote the repair upfront, and carry the common parts on the truck. In more than 26 years, we've completed over 200,000 residential and commercial projects — your furnace won't surprise us.

What are the signs your furnace needs a technician?
Your furnace needs a technician if you notice any of these signs:
- Cold or lukewarm air from the vents while the furnace runs
- Banging, screeching, or rattling instead of the usual low hum
- Burning or musty odors when the heat kicks on
- The furnace starting and stopping rapidly (short cycling)
- Rising energy bills without a change in usage — a struggling furnace works overtime
- The system won't start at all, especially on a cold night
What does a professional furnace repair involve?
A professional furnace repair starts with a full diagnostic: ignition system, gas supply and burners, blower motor, heat exchanger, filters, ductwork connections, and thermostat. You get a clear explanation of what failed and a firm price before we touch a wrench. Most repairs finish the same visit — our trucks carry ignitors, capacitors, motors, and the other parts that commonly fail.
Every heating repair includes a safety check for gas leaks and carbon monoxide, because a furnace that runs isn't the same as a furnace that runs safely.
Should you repair or replace your furnace?
A good rule: if your furnace is 15+ years old and the repair costs a substantial fraction of a new system, replacement usually wins. Modern high-efficiency furnaces cost meaningfully less to run, and qualifying ENERGY STAR models can earn SoCalGas rebates (up to roughly $2,000 on 97% AFUE units). We'll give you both numbers, honestly, and let you decide.
Furnace Repair FAQs
Why is my furnace blowing cold air? +
Common causes: a thermostat set to 'fan on' (circulating unheated air), a failed ignitor or pilot, a clogged filter causing the burners to overheat and shut off, or a failing control board. Some are five-minute fixes — a diagnostic visit sorts it out quickly.
Are furnace repairs an emergency? +
Losing heat with kids, seniors, or health concerns in the home is absolutely urgent — and burning smells or suspected gas odors always are. We run 24/7 without after-hours surcharges, so don't tough out a cold night.
How often should my furnace be serviced? +
Annually, ideally each fall. A tune-up cleans burners, checks the heat exchanger, tests safety controls, and catches failing parts before they strand you — and it keeps efficiency (and your gas bill) where it should be.
What's that burning smell when I first turn on the heat? +
A brief dusty-burning smell at the season's first start is usually just dust burning off the heat exchanger and is normal. A smell that persists, smells electrical, or smells like gas is not — shut the system down and call us.
